Redirect smtp traffic to ISP's mailserver

  • Hey folks. What i'd like to be able to do is redirect all outgoing traffic on port 25 to my ISP's mailserver as they otherwise block port 25. Often i'll have customers come in and try to send mail and it won't go unless I tell them to change their outgoing mailserver to our ISP's which is kind of a pain in the butt. Any suggestions? I seem to recall being able to divert packets in ipfw but couldn't figure out how to do it in pfsense. Thanks!

  • Create a portforward at interface LAN for port 25 to that server with ANY as external adress. Not sure if that works for a remote server. Maybe you need to forward this to a local mail relayer instead in that rule that is forwarding the traffic to that server then.

  • Looks like that will solve the problem just fine. Thanks hoba!
